We caught up with Rihanna on Sunday as she grabbed some coffee in Amsterdam. In a big fur hat, the songstress did, indeed, look tired.

The singer has been keeping busy in Europe -- in Paris late last week, Rihanna stopped at Lovestore, where she bought toys, handcuffs, scented candles and lingerie. Ultimately, the "We Found Love" singer bought $1,500 worth of items, says The Sun.

"She was grinning from ear to ear and seemed to be in a hurry to get back to her hotel," a source told the paper.

RiRi has reportedly been hanging out with the actor who played her love interest in the "We Found Love" video.

Back in July, RiRi visited Wicked Wanda's Adult Emporium in Ottawa, Canada, with her ex, Drake.
